The rapid expansion of oil palm (OP) has led to its emergence as a commodity of strategic global importance. Palm oil is used extensively in food and as a precursor for biodiesel. The oil generates export earnings and bolsters the economy of many countries, particularly Indonesia and Malaysia. However, oil palms are prone to basal stem rot (BSR) caused by Ganoderma boninense which is the most threatening disease of OP. The current control measures for BSR management including cultural practices, mechanical and chemical treatment have not proved satisfactory. Alternative control measures to overcome the G. boninense problem are focused on the use of biological control agents and many potential bioagents were identified with little proven practical application. Planting OP varieties resistant to G. boninense could provide the ideal long-term solution to basal stem rot. The total resistance of palms to G. boninense has not yet been reported, and few examples of partial resistances have been observed. Importantly, basidiospores are now recognized as the method by which the disease is spread, and control methods require to be revaluated because of this phenomenon. Many methods developed to prevent the spread of the disease effectively are only tested at nursery levels and are only reported in national journals inhibiting the development of useful techniques globally. The initial procedures employed by the fungus to infect the OP require consideration in terms of the physiology of the growth of the fungus and its possible control. This review assesses critically the progress that has been made in BSR development and management in OP.

油棕基底茎腐病的防治研究现状与展望。

油棕(OP)的迅速发展导致其成为具有全球战略意义的商品。棕榈油广泛用于食品中,并用作生物柴油的前体。石油产生了出口收入,并促进了许多国家的经济,尤其是印度尼西亚和马来西亚。然而,油棕很容易因灵芝boninense引起的基底茎腐烂(BSR),这是OP中最具威胁性的疾病。目前的BSR管理控制措施,包括文化习俗,机械和化学处理方法,都无法令人满意。克服邦尼氏菌的替代控制措施问题集中在生物防治剂的使用上,并且发现了许多潜在的生物制剂,但实际应用很少。种植抗博尼森菌的OP品种可以为基础茎腐病提供理想的长期解决方案。棕榈树对博尼氏菌的总抗性尚未有报道,也没有观察到部分电阻的例子。重要的是,现在已经认识到担子孢子是传播疾病的方法,由于这种现象,需要重新评估控制方法。为有效预防疾病传播而开发的许多方法仅在苗圃水平进行测试,并且仅在国家期刊上进行报道,从而抑制了全球有用技术的发展。真菌用于感染OP的初始程序需要根据真菌生长的生理机制及其可能的控制加以考虑。此次审查将严格评估OP中BSR开发和管理方面取得的进展。
